Host_Error: CMapLoadHelper::Init, unable to open maps/deathcraft_01_town.bsp

When I created server Counter-Strike did not have that problem because when my friends tried to get into my server, the game itself had to download the map and other files automatically from the server to the client.

To install the map on the server I copied the file (. VPK) to the folder "addons", and the maps appear already to play, but I would like the client do the download of this map automatically try to connect to the server. Isso sempre funcionou no Counter-Strike.
